Efficient Diffusion LLMs via Temporal-Spatial Parallel Decoding and Confidence Extrapolation

Zekai Li, Ji Liu, Yiqing Huang +3

Diffusion-based large language models (dLLMs) support parallel text generation via iterative denoising, yet inference remains latency-heavy because many steps are spent on redundan…

Slum Detection and Density Mapping with AlphaEarth Foundations: A Representation Learning Evaluation Across 12 Global Cities

Shuyang Hou, Ziqi Liu, Haoyue Jiao +7

Pixel-level slum mapping has long been constrained by limited cross-city generalisation, the absence of continuous density estimation, and weak global comparability. AlphaEarth Fou…
